Powershell - Unable to Compare Strings Output from Sharepoint List - arrays

Question

After extracting a list from SharePoint, I need to validate each Item against its BRTeam value. Here is the script:
cls
if((Get-PSSnapin | Where {$_.Name -eq "Microsoft.SharePoint.PowerShell"}) -eq $null) {
Add-PSSnapin Microsoft.SharePoint.PowerShell;
}
$sourceWebUrl = "http://theoracle/WorkingHere/"
$sourceListName = "Policies & Procedures"
$spSourceWeb = Get-SPWeb $sourceWebUrl
$spSourceList = $spSourceWeb.Lists[$sourceListName]
$spSourceItems = $spSourceList.Items
$spSourceItems | ForEach-Object {
Write-Host $_['Name']
Write-Host $_['BRTeam']
}
The code works fine in terms of getting the data and writing the required items to the host.
However, if I add the following If-Statement to validate the items, I am seeing an error:
if ($_['BRTeam'].Contains('HR')) {
Write-Host $_['Name']
Write-Host $_['BRTeam']
}
I have also tried replacing the Boolean check with $x -contains 'HR' after assigning $x = $_['BRTeam'], but this returns no output (no error either). Error below:
Method invocation failed because [Microsoft.SharePoint.Taxonomy.TaxonomyFieldValue] doesn't contain a method named 'Contains'.
At line:21 char:9
+ if ($_['BRTeam'].Contains('HR')) {
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : InvalidOperation: (:) [], RuntimeException
+ FullyQualifiedErrorId : MethodNotFound
Can anyone let me know what I am missing here?

I was able to resolve this by using the -Match operator instead:
$spSourceItems | ForEach-Object {
#Write-Host $_['ID']
#Write-Host $_['Workflow Started']
$x = $_['BRTeam']
if ($_['BRTeam'] -Match 'HR') {
Write-Host $_['Name']
}
}
If I am concerned that some other BRTeams may contain HR without actually being HR, I could also perform a -NotMatch against all the other departments.
E.g.:
$spSourceItems | ForEach-Object {
#Write-Host $_['ID']
#Write-Host $_['Workflow Started']
$x = $_['BRTeam']
if ($_['BRTeam'] -Notmatch 'Accounts' -And $_['BRTeam'] -Notmatch 'IT') {
Write-Host $_['Name']
}
}
