I get why Bloop is saying what he has said, because I worked in an industry where any time staff called in sick it was a fucking nightmare, and as the employer, it was just atrocious to deal with whenever it happened.
However, I frequently sent people home if they seemed even a little bit sick, and fully support people having a certain amount of no questions asked, paid days off with an MD note after 3 consecutive days.
Most people have illness or other shit that comes up in their life, and the stress of not being able to take a day off of work when it's really needed leads them to becoming embittered over time.
Now for me, taking a day off of work, like Bloop, was an ENORMOUS problem, so I never took days off unless I was violently ill. I just found a way to get there. But that's because I was doing high level, high paid, very satisfying work that I highly valued.
It was easy for me to prioritize my work over my own health because of what my work meant for me.
For most staff, that level of dedication is unrealistic and unreasonable. For a lot of jobs it's also totally unnecessary.
Bloop's response is to mandate staff into obligation, my response is to recognize that unless you are in a role like mine or Bloop's, minor illness and life shit just *is* more important to people than showing up to work sometimes.
If I had a staff member who was using up all of their paid time off days aka sick days, and got sick and had to take unpaid time off, then I would reassign that person to a role where them taking unpaid time off wouldn't damage the function of the business, perhaps reduce their hours and give them more flexibility if they're an otherwise valuable staff member.
Overall, when staff felt like their needs were respected, they called in sick less often, especially when they were in roles where it would hurt the business to be absent. The more loyalty they feel from their employer, the more loyalty they have to their employer.
Or you can just rule with an iron fist and foster a culture of resentment. That's usually the option people go for.
