Employees  shall  have  the  right of
  self-organization, to form, join,  or  assist  labor  organizations,  to
  bargain  collectively through representatives of their own choosing, and
  to engage  in  concerted  activities,  for  the  purpose  of  collective
  bargaining  or  other  mutual aid or protection, free from interference,
  restraint, or coercion of  employers,  but  nothing  contained  in  this
  article  shall  be interpreted to prohibit employees from exercising the
  right to confer with their employer at any time,  provided  that  during
  such  conference  there  is  no  attempt  by  the  employer, directly or
  indirectly, to interfere with,  restrain  or  coerce  employees  in  the
  exercise of the rights guaranteed by this section.
