However, when migrants first arrive in Finland, their ability to productively use their skills in employment tends to be compromised by limited language skills, lack of familiarity with the labour market and, in some cases, poor health. Where wages are able to respond to productivity, lower productivity should not necessarily compromise employer demand. In Finland, however, where collectively-bargained minimum wages act as wage floors, employers hiring those whose productivity is temporarily compromised by limited language skills, are unable to adapt wages accordingly. This is particularly true because foreign-born workers in Finland are heavily concentrated in the lowest-paid positions where collectively-bargained minimum wages bind (over 40% are concentrated in the lowest income quintile).
