Is there flexibility in work hours.

flexibility is really limited considering we're only open 10 to 7 overall they do work with you if you have to run a little bit late maybe leave a little bit early as long as it is not a routine they do try to work with you the best that they can depending on how busy it is the manager and Staffing of course

Aside from vacation and medical appointment time, absolutely not. Mandatory overtime is common, up to 49 hours a week in Cx service. Off days can be cancelled. This is the worst part of Cx service/tech support. Many have FMLA to avoid this and get time off as needed due to horrendous work/life balance and scheduling.

This flexibility depends completely on your leadership team. As a company (at least in retail sales) there is zero flexibility built in to policy. This means that an overbearing manager can completely ruin your work/life balance

Most of the time until a deadline looms

Yes, depending on function
