I'm currently on long term sick from work, 10 weeks, due to post Covid issues.
I'm planning to return soon, to a professional job, that I work 4 days a week at, average UK pay, but one that is extremely demanding, out of hours crisis stuff. During the 10 years I've worked there, my workload has increased considerably, and I've noticed that in similar roles elsewhere, the workload is shared among a team, whereas all the burden sits with me, there is no cover etc. The comparable roles all pay substantially more for my skills too.
I haven't enjoyed it for a while. I work alongside senior management, we all look after an area, only they are on more than double my pay, with their own teams to delegate to, which makes the crisis requirements possibly easier to handle.
I had wanted to leave my role pre Covid and work elsewhere in the same libe of work, but after what will be 3 months on sick leave, I now feel unemployable and that another employer will not want me (late 40s) with such a lengthy sick leave record. I have a good amount of experience and training in my field, and pre Covid, my attendance was consistently high, averaging 0-1 days off sick a year.
I cannot face returning to a role that was so stressful. I would like to reduce my hours further to 3 or 2.5 days (maybe job share?) so that I could try my hand at freelance work on 2 days a week (my area of work lends itself well to this) and maybe build up a business that I could do full time eventually, given that I feel no other employer would want to take me on now.
Am I able to submit a flexible working application while off sick, or would I need to wait until my return?
Is this a sensible plan (the alternative, as I am now unattractive to employers, would be to leave and just take any job)?
Thanks in advance.
