My current working negotiated hours are 830-430pm. I returned from maternity leave with childcare pickup close to work for 5pm, which was the best option i found. 2-weeks after returning from mat leave, I experienced back to back extenuating out of my control situations regarding my childs daycare resulting in suddenly having no daycare & then a personal medical emergency involving me in and out of hospital treatment for 3 weeks. Immediately on my return to work from hospital care, i requested family status accommodations for childcare pickup to shift my hours 30 min. as the new place requirement is 430 pickup near my home; as well as other suggestions to accommodate this with minimal work disruption that allows me to still complete my job effectively. My boss verbally told me hours wouldn't be an issue prior to signing on to this new daycare as I was upfront about it all as it happened in live time. They are now saying they will only accommodate me temporarily and requested i find new solution that accommodates new working hours 9-5pm within 6 weeks. I responded saying the totality of the situation, how stressful this has been for me and that i've been doing everything in my control to minimize disruption, but what they're asking for isn't possible. I provided explanation as to why my partner is not able to arrange childcare (his job is more managerial and senior so he's relied on differently - no one else can do his job and it's not predictable or reliable for picking up). They said that wasn't good enough and can appreciate what i'm dealing with but ultimately added now working pressure that doesn't feel necessary because they want to "align the team on more consistent hours". I said i originally negotiated these hours with the company prior to starting because a 9-5 schedule would never have worked for my family life style and they responded they didn't realize how disruptive the difference would be. Meanwhile they also admitted it's not about my work ethic, or ability to perform exceptionally - it's simply them wanting every staff member to work 9-5 because that's what the industry expectations are? I offered to work evenings after pickup for any work that needs to get done and deadlines in advance, childcare can be arranged, but it's not a permanent solution because i have no one else. They told me to find a nanny which i cant afford or some random other person to keep my child for 2 hours until i get home. My goal was never to spend less time with my child and they're using my return from maternity leave and having family responsibilities against me. They kept commenting how other people work late regularly and it's not condusive to the team to have to leave exactly on time every day - but i'm not paid for overtime work and that shouldn't be the expectation. so even working my 830-430 prenegotiated contract terms is not sufficient for them because they want someone more flexible. I dont know what to do - i'm overwhelmed. running on empty and exhausted. they just added another level to my already stressful situation and they are not being asked to accommodate me in anything close to undue hardship so it's super unreasonable and to make me jump on it immediately upon returning from the hospital after i haven't even settled back in yet is unreasonable.
