Yes they can tell you that you have to come in.
Each employer's policy is different
If the note is with your employer, possibly and probably, but it depends on the wording of the note. If the note is with a third party, a court can order a garnishment, but the wording of the note will again come into play.
can a employer contact you while you are covered by a sick note
HIPAA prohibits your employer from contacting your doctor directly. The emplopyer can comple YOU to get the info from your doctor or can hire a doctopr to contact your doc.
If you missed your first day of work and you haven't done your employer the courtesy of calling to say why you weren't going to show up, I'd predict that you won't need to worry about getting the note since you won't have the job.
After the note has been signed and approved, you don't have a whole lot of leverage. It may be too late to do anything about it - but - it wopuldn't hurt to talk to the lender and ask that certain facts not be disclosed to your employer.
They can try to call them, but the doctor is not allowed to give out any information about you. The doctor might be able to say "yes s/he came in today"/"no s/he didn't come in". But the doctor is not allowed to give out the reason why you went in, since this would be a breach of the Doctor-Patient Confidentiality and therefore illegal. In summary- The doctor can say whether you have seen him/her on that day. But the doctor cannot tell the employer why, if you did, you went to see the doctor, unless the doctor has your permission to do so.
You're allowed 3 call offs without a doctors note. But the third one will result in a 3 day suspension. You can call off as much as you like as long as you have a doctors note.
they sure can, the note simply clears up all questions. is he sick? is he lying? the dr.s note, immediate family member death, or being in a coma, are the only reasonable excuses for leaving or not coming to work
note on resume in general from employer's point of view
no
only if you are already having a conversation but don't call them or have the first thing come out of your mouth next time you see them be about that
